(1987) perception can be very effective not always leads to superior performance but the conditions characteristics of complex work domains are propitious for perceptual processing Ecological Interface Design (EID) The Propensity for Perceptual Processing Two Examples Klein(1989) a series of naturalistic DM in the domain.
